SOURCE: I have no power to selanoid it is a 1993 gmc 3500

there could be a bad wire somewhere between the solenoid and battery. that is the only thing i can think of if you have done everything else. I will lean towards starter relay, it should be in fuse box. if not that I would check for a bad ignition switch. not letting power to go to starter. good- day !!

1993 gmc suburban rough idle, stall in reverse


Idle air control (IAC) control rpm idle during idle.

Test it on idle with ALL electrical on full force.
RPM should increase.
If RPM remain the same then IAC is question.

Low lever rpm rate is hight(8)


The relation between torque, power and angular speed is

Power falls off below a peak located at high engine speed, because less fuel/air (energy source) is brought in and burned per second. If that were the only factor, then power output would be proportional to angular speed

1798043-1.png

and torque would remain constant down to idle. In fact passenger car engines have a fairly broad and flat torque curve.However engine efficiency drops with at low speeds since combustion chamber shape, bore/stroke ratio, manifold runner shape and length, valve lift and intake/exhaust valve overlap, to name just a few factors, are tuned for best performance at higher engine speeds. Thus torque eventually falls. In racing cars, the tuning is "peakier," that is, they produce far more peak power but only over a narrow RPM range. As you might expect, the torque curve isn't as flat in this case, and it falls off more rapidly. Vehicles that are optimized for very high torque at very low vehicle speed either have no high end to speak of (road graders, bulldozers) or, if they need both, use different systems (diesel-electric locomotives

1993 gm 454 engine fan belt assembly


Go to www.autozone.com and click on repair info and enter in car info and then click on repair manuals and a manual for your vehicle will come up and it should be listed in that manual. Sometimes the diagram is on the hood of the vehichle rather than on the engine compartment but you probably already looked there... Hope this helps
